After dominating his opponent, John Dodson, in the championship rounds of their fight, Mighty Mouse scooted out of the Octagon with an impressive unanimous-decision victory.

The champion faced moments of adversity in Rounds 1 and 2, but he took Dodson's best shots and kept moving forward, a testament to his heart and competitive drive.

After the victory, there is literally no legitimate contender that he has not already defeated in UFC action, and for that reason, he is primed for a lengthy stay atop the 125-pound division.

The UFC is littered with dominant champions right now, and Mighty Mouse has given us every reason to believe he will continue this trend at 125 pounds.

The first reason this will hold true is the fact that he obviously does not have human lungs. Nobody should be able to push the pace he does for the amount of time he does, but Mighty Mouse somehow does it.

He's quick, he's explosive and he is dangerous from minute one to minute 25 in a fight—and that is an impossibly difficult task for his challengers to overcome thus far.

A five-round fight works to his advantage, and that is all he will be seeing in the near future.

Secondly, the flyweight division is too thin right now.

The only reasonable challengers to Mighty Mouse's championship strap are fighters he has already defeated.

Joseph Benavidez and Ian McCall will square off at UFC 156 in a bout that will likely determine the next challenger. Outside of those two, one can point to John Dodson, who, despite failing to capture the title, showed that he can pose a threat to Mighty Mouse on the feet.

After that, one is hard-pressed to choose another top contender. Do you go with John Moraga, a fighter who is 2-0 in the UFC, with his best win coming at UFC 155 over Chris Cariaso?

Maybe you can point to powerful grappler Darren Uyenoyama, a flyweight who is also 2-0, with his wins coming over NorifumiYamamoto and Phil Harris.

You are saying "who?" a lot—don't lie to me or yourself.

This point perfectly illustrates the lack of depth in the flyweight division, and it is the main reason Johnson will remain the champion.

He will be heavily favored in his bouts for the foreseeable future due to the fact that he has already defeated any worthy challenger—sound reasoning, no?

Johnson is phenomenal, and he is only getting better. The flyweight division, however, is not getting deeper at a fast enough rate to make up for the skill disparity between the top four guys and the rest of the division, so we are unfortunately stuck in this pit of rematches until further notice.

All this considered, Mighty Mouse looks to be every bit the longtime champion that we see in the UFC's featherweight, welterweight, middleweight and light heavyweight divisions.

With a skill set that is perfect for his division and no real challengers on the horizon, it would be foolish to expect anything less.
